Recently I noticed a new trend in the Web 2.0 aggregation tools. These are tools which combine other web 2.0 services in one place and provide a way to host a single page containing all your services. The most common services provided by these aggregating tools are combining delicious, flickr, blogspot and rss feeds in one place.
I found an inherent problem in these services.
What I tried to do is to set up a page which contains feeds of my interest based on various other tag search results. In particular, I wanted it to aggregate feeds from delicious, Technorati, Google blog search, Yahoo news search, Feedster, Icerocket etc. I wanted search results for:
(semanticweb OR semantic-web OR semweb OR sw OR semantic_web) AND (owl OR rdf OR rdfs OR ontology OR ontologies OR taxonomy OR rdql OR SPARQL OR w3c OR metadata OR semantic OR semantics OR knowledge)
These are the problems I faced:
* Most tag search engines are not intelligent enough to provide RSS feeds for such searches.
* The page is not intelligent enough to remove duplicate links. For example, suppose I have a page bookmarked in delicious having the tags as semantic-web and rdf, then that particular link shows up in both the tag searches. So if I combine the tag search results, the page shows up twice.
* Most of the service providers do not have an option to turn off non-English pages. So many Japanese and French (or Latin?!) pages turn up in the results.
* I want a hierarchy. I should be able to create a group “Semantic web” which contains feed results for the search query given above and another group, say “Web 2.0” which has a similar query. I should be able to relate the results of “Semantic web” group with those of “Web 2.0”.
* The ability to view feeds using different views – “Technical” and “Non-technical” or “Office related” or “Non office related”.
* Finally, there should be a theme. I would like to read my “Technical feeds” once a day and “Comics” once a week. How do I separate them?
I am still looking for a solution.
